Three-Dimensional Localization of a Near-Field Emitter of Unknown Spectrum, using an Acoustic Vector Sensor Corrupted by Additive Noise of Unknown Spectrum

Abstract

Algorithms are developed to estimate a near-field wideband emitter's azimuth-elevation direction of arrival plus radial distance, based on data collected by one acoustic vector sensor. These new algorithms need no prior knowledge of the spectra of the incident source nor of the temporally colored noise.
